Cisco Switches :: SGE2010 Switches - Best Way To Implement Redundancy

Oct 31, 2012

I currently have two SGE2010's with a 4-port LAG configured between them.  I'm looking to add another two SGE2010's and I want to add redundancy at the same time.  The switches are currently in standalone mode.  I don't have fiber connectors and was planning on just using copper for the uplinks.
 
My questions are:
 
- Is it possible to use stack mode in conjunction with 4-port LAG groups to create redundant 4-port links between all of the switches?  The documentation says that ports 24&48 are reserved for stacking - does that mean I can't specify a LAG instead?
 
- If 4-port LAGs aren't possible, does that mean that these switches max out at 1Gpbs uplinks if you use stack mode?

Cisco Switches :: SGE2010 Switches / VLANs And A Blocked Port In Spanning-tree?

Aug 20, 2012

I have 2 switch groups.
 
2 SGE2010's with VLAN's defined as 10,20 and 30
 
Vlan 10 is the management VLAN, and it uplinks to our border router.Vlan 20 is the workstation VLAN, and all workstations point to the switch as their default GW? Vlan 30 is the ip phone VLAN, and all phones use this as their gateway.
 
I would like to put a LAG between said switches, we have some servers on the ip phone switch that need to be accessed by the workstation clients, and the single 100mb link through the router is probably not going to be enough.As I understand it, because the switches have different networks on them, a simple lag will not work. I did create a lag, and assign ip addresses to each side, however in that mode, it doesn't appear I can block vlan 10 from transiting the LAG, and with out that block I will end up with a logical loop, and spanning-tree will block one of the uplinks, or the LAG itself.

Cisco Switches :: Cannot Bind ACL To Interface On SGE2010

Aug 30, 2011

I am working on two SGE 2010 stacked and in routing mode. Everything work fine but before finishing the job, I wanted to lockdown all the network device so they would not be accessible from some subnets. Problem is, I cannot bind my ACLs to any interface. I get "Cannot apply because lack of HW resources." I am running firmware 3.0.0.18, and 3.0.1 release notes don't address that issue. TCAM utilization is at 3% Routing resources shows host: 200, routes:60, ip interfaces: 50 I have tried from the cli and get the same message.

Cisco Switches :: SGE2010 - Cannot Get DHCP Working

May 28, 2013

We have a single SGE2010 in layer 3 mode switch with a Server 2008 DHCP server.
 
We will be implimenting a Voip netowork where the PC's connect to the voip phone. I would like to create another vlan - 10. I have created the vlan and assigned the IP on the swtich.
 
Routing seems to be working. I can ping both IP addresses of the switch on either vlan.
 
I cannot get DHCP working. In the SGE switch I have enabled DHCP Relay, enabled option 82, set my DHCP Interface as VLan1, and specified the DHCP servers IP address. On the ports I have set the port where the DHCP server connects to as a trunk port with Vlan 1 untagged and vlan 10 tagged. I have set the ports where the phones connect as a trunk port with vlan1 untagged and vlan 10 tagged.

Cisco Switches :: SGE2010 How To Trigger Backups Via SNMP

May 15, 2011

I have been trying, so far unsucessfully, to trigger backups to a TFTP server of our SGE201 switches. I have testesd TFTP backups via the web interface, and that does work. I need SNMP as I  need a scriptable method to trgiger the backups on a regular schedule. I am running the SNMP query from a RedHat Linux server. So far I have the following query work out, but it is failing: [code] The error I am getting is generic, and the same query failed on multiple switches running Software Version 3.0.0.18. The switch is set with the community having full SNMP-admin access from the server's IP address.

Cisco Switches :: SGE2010 Does Not Block Ports Even With STP Enabled

Jul 28, 2011

We are experiencing bridge storms and network slow downs and we believe we have traced the issue down to users plugging a cat 5/6 cable between 2 ports on the wall both wired back to a SGE2010 switch.
 
So we did a test - we plugged a single short cat 6 cable between 2 ports on a SGE2010, our access switch. Suprisingly, even with STP enabled, the switch DID NOT block one of the ports and in a few minutes the ENTIRE NETWORK was down, as CDP, STP, and ARP traffic became a multi-gigabit storm throughout the network.
 
Why on earth does this switch not block a port that is obviosly looped?
 
Every other cisco switch since I started on 1900XL's did this in 1999.

Cisco Switches :: AP514N And SGE2010 Configuration For Vlans

Dec 10, 2012

Id like to set up our AP to push our different vlans depending on which ESSID you connect to.
 
A few things I am unclear on. The switch port on the SGE needs to be in trunk mode I assume.
 
Do I marry the Management Vlan ID on the AP to the PVID on the SGE port ? Or is the PVID the untagged vlan ID ?  
 
I set the switches port to trunk mode, it's PVID to 10 and set the management vlan ID on the AP to 10 and I get TTL Exceeded in Route when I try to ping.

Cisco Switches :: SGE2010 Inter VLAN Routing

Oct 3, 2011

I've recently installed an SGE2010 switch, which I have set to 'Layer 3' mode.
 
I have created 2 VLANs using 192.168.10.x and 192.168.20.x (using .50 for the VLAN IP address in each case) - however, I need to be able to allow certain traffic between the VLANs.Alternatively, to get things started - I'm assuming I need to set up ACLs to allow access between VLANs - how would I configure the switch to allow all traffic from one VLAN to the other?

Cisco Switches :: SF 300-48P How To Implement Route

Oct 13, 2011

We recently purchased a SF 300-48P to replace a Layer 3 3Com switch that died. I've sucessfully put the switch into Layer 3 mode and assigned ip addresses to each of the VLANs but I cannot figure out how to implement routes for those. Here's some info on our network and what the previous switch had. [code]
 
Not sure if this can be translated into the Cisco or not.. If i try to create an IP route like these i get errors that the Gateway can be a route.

Cisco Switches :: SGE2010 Clients Need To Route Through ASA 5505 And 3750

May 17, 2011

I need to move the client machines off of the 3750 (and their DHCP dependency on it) to the SGE2010 and absolutely route their internet traffic out through the outside interface on the 5505. They must also be able to communicate back into the internal environment in order to communicate with the production servers.
 
The clients currently use .254 addressing through a dumb dell switch to the 3750 but I am trying to migrate them over slowly to the .253. I know that the 2010 will not do DHCP, so I am putting a DHCP server on that switch right now. The 5505 won't let me add an additional nameif statement onto one of the other eth0/x interfaces and I'm not sure if that has anything to do with it's capabilities to act as a DHCP server (it's not an option in the ASDM) or it's ability to serve as the internet gateway for the 2010 clients. (Side notes: The 5505 has a base license and is currently also connecting 1 site to site VPN. As is the 5520, so all of it's interfaces are used as well).
  
I statically assigned a moved client with a .253 address and plugged it into the 2010. I have tried giving the 2010 both a .4 address and a .253 address but neither will allow me to ping any of the addresses on the 5505. The 2010 shows automatic routes to the two subnets and I set it's default route to 253.1. The link between the 2010 and the 3750 works - clients receive a .254 address from the 3750 and can get out to the internet via the 5505 and reach the production servers as well.
 
Why won't the 2010 see the 5505 as a gateway and allow clients to get to the internet and also traverse the 3750 when they need access to the production network?
 
The reason why I dont' just connect the two swtiches and call it a day is because I also need the production servers to ALWAYS go out/receive web requests via  the 5520 outbound/outside interface. I'm having such a hard time wrapping my head around why i can't get my clients moved over to the new switch, I haven't even grasped how I'm going to do that yet.

Cisco Switches :: Set Up SGE2010 Combined With Dell 6248 Switch?

Dec 14, 2011

I have currently a Dell powerconnect 6248 switch combined with a netgear UTM router. I have a basic understanding on how things should work but I don't have the knowledge to apply it as I'm new to setting up vlan and the person before me did the basic configuration like this:
  
defined 5 VLAN in the netgear router

defined the same 5 VLAN in the dell 6248

connected the dell switch to the netgear router via a trunk port.
 
Right now all the inter vlan traffic pass thru the netgear router as the dell switch as a trunk port connected to the netgear box who then give dhcp and set himself as the default inter vlan route. I would like to stop that since I would like the cisco switch to handle all the vlan routing for both switch and those switch to send their dhcp request to my win2k8 server.

I did set the sge2010 in layer 3 mode from the small business telnet interface. I then setup the same 5 vlan in the cisco switch.
 
If I understand this well I need to define an IP address for each vlan interface on the cisco switch for it to be able to route things, I have set them all as x.x.x.3 (x.x1.3 vlan 1, x.x.2.3 vlan2, etc) Then I need both swtich to forward all dhcp request to my dhcp box wich is in vlan 2. My DHCP server will have 5 range of IP address to hand out. my server are connected directly to the dell switch on vlan 2. I have set up a port in the dell switch in trunk mode and did the same thing in the cisco switch and connected them togheter to send all vlan packet. The current setup doesn't work so I need to finalize that setup so that everything works.

Cisco Switches :: SGE2010 Stacking Versus Link Aggregation?

answer regarding stacking the SGE2010 switches versus link aggregation if greater than 1 Gb connectivity is required between individual switches? Currently have several switches in a stack configuration but would like to increase the bandwidth between some or all of the switches. Does stacking support a link aggregation configuration? If so what ports can be used and how should the link aggregation be configured in conjunction with the stacking?

Cisco Switches :: SGE2010 - Firmware Upgrade And Configuration Not Saving?

Oct 7, 2012

Using the SGE 2010 for Microsoft NAP with 802.1x auth for switch access, which led to a few issues
 
What i have: An SGE 2010 48 port switch, firmware 3.0.0.17 Firmware upgrade: In order to ensure im not having problems due to old firmware, i tried to upgrade using ros_ls1_bp_ge_bx-3020.ros in order to move to 3.0.2, when uploading the file via TFTP, the upload completes and thats it, nothing happens.Restarting the device: As part of the upgrade process, i thought i might of had to reboot, so i rebooted, and found that all my settings were wiped clean, as if a factory reset had been performed.... and add further to pain, the backup of settings that i had taken do not seem to want to re-apply.NAP support: So i have tested my NPS (radius) server with NTRadping.exe and all is good, however i cannot get the SGE2010 to talk to it.... the authenticator state in the web interface is always listed as initialising.... im not sure if this is a simple incompatibility (hence the attempt at a firmware upgrade), a tag that needs to be set on the radius side or a switch misconfig.

1) how on earth do you upgrade the firmware?

2) why are none of my settings being saved when the device reboots ?

Cisco Switches :: What Traffic Is Carried Over SGE2010 Stack Link

Nov 11, 2012

I have several SGE2010P switches connected in a stack. They are working fine as a stack.
 
Question is - what traffic, besides stack control, is carried over the stacking links?
 
All unused ports are VLAN 1U. Ports in use belong to VLANs 100, 101, and 105.Since I cannot configure or see the stacking ports, I am unclear if any non-default VLAN traffic passes over those links between switches?

Cisco Switching/Routing :: SGE2010 Switches Stack Dropping Ports

Oct 12, 2012

Our environment consits of 4 cisco SGE2010 switches (stacked). I have implemented STP BPDUGUARD and Portfast on all client ports (suspected a loop). And our uplink to the Server DMZ recieves almost all of it's BPDU packets back(is that normal?) The issues lies where we have random ports dropping out - across all stacks for seconds at a time. We get errors/warning such as,Pinging between the DMZ network appears to be fine. Pinging from the client/switch network show packets being dropped quite frequently.All devices are on VLAN1 (I've have researched this and this could be the cause of the issue)

Cisco Switches :: SGE2000 And SGE2010 - Change Names Of Interface To Unique?

Nov 7, 2012

We've been trying to monitor the used bandwidth of our SGE2000 and SGE2010 switches with Nagios.We've been experimenting with the various OIDs and we've found the OIDs linked to the different switchports.
 
Though when we use SNMPWalk (to find the OIDs connected to the port) the names of the ports are all the same.
 
[code]....
 
Is there a way to change the names of these interface to unique names?We've already given unique names in the description field through the switch's GUI, but it doesn't make any difference for Nagios.
